Answer:

Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is

we have
----> the radius is half the diameter
substitute


step 2
Find the area of a sector
Remember that
The area of the circle subtends a central angle of 360 degrees
so
using proportion
Find out the area of a sector with a central angle of 108 degrees

assume

substitute

In order to find the total number of roses, we can use multiplication. Since there are 6 roses on each bush, we can say that the answer is: 6+6+6+6+6+6+6+6+6+6. Since multiplication is a way to quickly add the same number, we can use 6*10. This becomes 60.
Good luck :D

Answer:
a ∥ b
Step-by-step explanation:
The symbol "∥" means parallel lines.
Taking a look at the figure above, we have 2 parallel lines, labelled a and b.
A and B are two points on line "a", forming segment AB. However, segment AB is part of line "a".
Same applies to line "b", which has 2 points forming segment CD.
Therefore, the correct label if the parallel lines is a ∥ b
